NPC Avatars
Finally got around to adding some NPCs into the game. Currently you can chat with them. Soon, they will be used to start quests, and to provide rewards, etc. It’s very cool that I have this working, since enemies will … Continue reading

Large Mesh Files
I decided to re-write the mesh load and save routines used by the engine. They were previously using a recursive algorithm, which quickly caused the stack to fill up on larger models with deep hierarchies. Running into a stack overflow … Continue reading

Collision and Response
I’ve been hard at work implementing new intersection tests, and dealing with collision and response algorithms. Pretty tough stuff to make work correctly and smoothly under all circumstances! I’m basically breaking up an area into distinct height levels, then doing … Continue reading

Been There Radar Window
